PURPOSE:To easily adjust and control the driving stroke by forming a diamond- shaped lever by four levers, interposing a linear actuator between both elbows of one opposite angle and connecting therebetween. CONSTITUTION:The respective end portions of each pair of arms 2, 3 on both sides are movably connected to each other to form a diamond-shaped lever 7, and a linear actuator 8 is interposed between both elbows of one diagonal. In this arrangement, as the turning radius of the diamond-shaped lever 7 can be adjusted by controlling the supply of compressed air to the linear actuator 8, the stroke of drive motion can be easily adjusted so as to improve the reliability.
